Control Channels
* Special commands require that the DMX512 value be held for three seconds, followed by an immediate change to
DMX value 0 without any other values in between.
** When the control channel stays at this value for three seconds, the shutter controls are mapped to the SDI Configura-
tion for Shutter Control. The configuration values are stored by the Mbox Extreme application. Change the control
channel value to restore normal shutter functions. Video card gamma works in all full screen modes - not just SDI.
